Researchers report nanoscale energy-efficient switching devices

By relentlessly miniaturizing a pre-World War II computer technology, and combining this with a new and durable material, researchers at Case Western Reserve University have built nanoscale switches and logic gates that operate more energy-efficiently than those now used by the billions in computers, tablets and smart phones.

Triboelectric generators capture wasted power (w/video)

With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs - with no batteries or power cord. The current comes from essentially the same source as that tiny spark that jumps from a fingertip to a doorknob when you walk across carpet on a cold, dry day. Wang and his research team have learned to harvest this power and put it to work.

Optical techniques for accurately determining the toxicity of nanomaterials

EPFL researchers have developed a method for accurately determining the toxicity of nanomaterials. By using optical techniques, they are able to measure the concentration of the oxidizing substances produced by a damaged cell. Furthermore, this research also offers a new way to know more about the mechanisms of oxidative stress.
